I think the dime is to big for an Example so lets use a Focus adapter ring to help you picture how small it really is.

'The Mini'

"X-Boost V7"

Just wanted to show this latest Boost Drive that i made.

Most of you guys have all seen my X-Boost. Its nothing New.

Here is a slightly different version using a Different chip and design in order to get it smaller.

It is pot ADJ and can boost up to 1.8A for 445nm down to 3.6v-3.7v off 1 single driver. No need to dual. As well as run 12x diode, Single Mode Blues etc....

The Pot is a Nice and Beefy. Very forgiven. In other words its easy to set and no need to search for a tiny screw driver.

But there is also another cool thing about this driver. The Pot can also be Removed or not put in place and now the laser Driver becomes Fixed for those that hate pots and would rather have a fixed driver and there is no need for any extra modification. Just as simple as that. "I dont really care for Pots"

The Driver was designed simple for Size. Get it as small as possible.

Right now As you can see below its very small. 10mm x 12mm which puts it 1mm larger then the Flex drive/Micro Boost to give you a prospective. It will be getting even smaller then this just need some more time to play with it but for now iam pretty happy with it.

It can fit in most of the hosts out there that you would use such a driver for and fit in the back half of an Aixiz Module.

Hey thanks guys. GLad you like it. It was was a fun long project to do.

Nothing beats looking at your finished board when your done.

Those DFNs really suck. I would go crazy if I tried to make a large batch of drivers with those chips.

Thanks Buddy.

Oh tell me about it. I hate them. They never re flow right in the over and hot air seems to be the best and only way because you can move them around. Even then by the time you do 1 driver alot of time has passed. Must think of a faster method.

Perhaps try a batch on a hotplate?
Reflow the DFNs on the hotplate & do the other side in a toaster. Epoxy the little monster if it tends to move during 2nd reflow.
